- Abyssal Zone
- Neritic Zone
- Benthic Zone
- a A layer in a body of water in which water temperature drops with increased depth faster than it does in other layers.
- b A method of desalination where ocean water is heated to remove salt. Heat causes liquid water to evaporate and leave dissolved salts behind. When the water vapor condenses, the result is pure fresh water.
- c Has no sunlight because it begins at a depth of 4,000 meters and extends to a depth of 6,000 meters.
organisms that live there: sponges and worms
- d The bottom region of oceans and bodies of fresh water.
- e The area of the pelagic zone above the continental shelves. Has abundant sunlight, moderate temperatures, and relatively low water pressure.

- Begins at the continental slope and extends to a depth of 4,000 meters.
animals that live there: octopi, sea stars, and brachiopods.
- A method of desalination where water is frozen. Then the first ice crystals that form do not contain salt. The ice can be removed and melted to obtain fresh water.
- A process of removing salt from ocean water.
- All organisms that swim actively in open water, independent of currents
- The mass of mostly microscopic organisms that float or drift freely in the waters of aquatic (freshwater and marine) environments.
